3 Claims.

This invention relates to an attachment for use with stitching machines.

One of the objects of the invention is to provide an attachmentadaptable for use with carton 5 stitching machines.

Another object of the invention is to provide an attachment adaptable tocarton stitching machines comprising carton blank holding and securingmeans.

Another object of the invention is to provide an attachment of thischaracter which is simple to construct and operate and inexpensive tomanufacture.

Other objects of the invention will be apparent from the description andclaims which follow.

The attachment of the present invention is adapted for use withstitching machines used tor assembling fiber board cases which aresecured by wire stitching or metallic fasteners.

By way of illustration but Without limitation the attachment of thepresent invention will be described for use in assembling fiber boardcases comprising end members and a one-piece body member forming thesides of the carton.

In practice, it is customary for the operator to stand before themachine with a supply of carton end blanks on a table at his left and asupply of carton body members on a table at his right. With thisarrangement, the operator in assembling each carton is required to turnapproxi 'mately'90 to the table at his left to pick up an end blank andthen turn back to the machine to place the end blank into a clip beneaththe stitching head. The operator then must turn ap- 85 proximately 90 tohisright, pick up a body member, form it into shape, turn back to themachine, place the body of the container around the end blank previouslyplaced in the machine and then stitch to fasten the end blank within thebody 40 member. The operator then must turn 90 to the right, place thepartially formed container on the table, turn approximately 180 to thetable at his left, pick up a second end blank, turn approximately 90back to the machine to place the to second end member in the machine,turn again approximately 90 to the table at his right, pick up thepartially formed container, reverse the ends of the container, turnapproximately 90 back to. the machine and stitch in the second end.

0 In accordance-with the present invention there is provided a shelf forholding a pile of carton end blanks and a carton end blank holding meansat either side of the stitching head. There is further provided belowthe stitching head an 5 adjustable shelf on which is arranged a supplyof carton bodies. By use of the attachment of the present invention theoperator standing at the machine is. enabled to reach forward and in onemovement to pick up an end blank in each hand. One of the end blanks isplaced on the 5 anvil and beneath the stitching head and simul--taneously the other end blank is secured in the carton end blank holdingmeans arranged toone side of the stitching head. .The operator then withanother movement forward is enabled to 10 .pick up a body member, formit and place it around the end blank beneath the stitching head andstitch the end blank into place. The operator then removes the partiallyformed container from the stitching machine, reverses the ends of 15 thecontainer and again with a forward movement places the unstitched end ofthe body memher around the end blank previously secured in the holdingmeans. The container and the second end blank are then removed from thesecur- 20 ing means, placed in the machine and stitched.

Use of the attachment of the present invention enables the operator toeliminate the many turning movements of his body and thus provides amaterial saving in time and labor.

Reference is had to the drawing in which like characters of referenceare used to designate similar parts.

Figure 1 is a perspective view showing a carton stitching machine withwhich the attachment of 30 the present invention is employed.

Figure 2 is a front view of the machine and attachment shown in Figure1.

Figure 3 is a plan view.

, Figure 4 is a view taken substantially on the 35 line 4-4 of Figure 2.

The stitching'machine illustrated in the drawing may be of theconventional type comprising standard I, stitching head 2 and anvil 3.As shown in Figure 3, a track 4 may be welded or 4 otherwise'rigidlysecured at one of its ends as at 5 to either side of standard I. Thefree ends of tracks 4 are supported upon risers 6 rigidly secured as bybrace rods 1 and 8. It will be understood, of course, that tracks 4 maybe of the portable type and need not be in any way affixed to thestitching machine.

Carton end holding means 9, comprises a fiat relatively rigid ledge ofsheet metal or other suitable material and is extended forwardly fromeach of the tracks 4 substantially in parallel relationship with anvil3. Ledge 9 may be welded or otherwise rigidly secured to track 4, or, ifdesired, may be adjustably secured to track 4 by use of plate I0 andbolt H for movement from and toward the stitching head to a positionbest'suited to the operator. Also, ledge 9 may be angularly bentdownwardly as at I2 to facilitate removal of the carton end memberstherefrom.

As shown in Figure 4, ledge 9 is provided with resilient spring clamp I3for removably holding the carton end members thereon. Also, a shelf I4for holding a pile of carton end blanks provided with retaining walls I5is rigidly secured to the upper surface of ledge 9 as at I6.

Container body supply shelf I1 is secured to standard I as by screw I8threaded within one of the openings I9 provided in standard I. Theseveral openings I9 allow for vertical adjustment of shelf H to suit theconvenience of the operator.

In the drawing, there is shown a track 4, a ledge 9 provided with a clipI3 and a shelf I4 provided at either side of the stitching head. Thedual provision of these elements in this manner is for convenience only.In the formation of each carton, only one ledge 9 and clip I3 is broughtinto use. Likewise, with the provision of a single shelf I4 the operatorupon reaching forward may in a single movement seize an end member firstin one hand and then a second end member in the other hand.Consequently, it will be seen that the provision of a single rack, ledgeand end blank supply shelf will serve equally as well for carrying outthe purpose of the present invention.

I claim:

1. In combination with a carton stitching machine including a standardprovided with a stitching head and anvil extending forwardly insubstantially parallel relationship from the standard, a track securedto the standard and a carton end blank holding ledge adjustably mountedon the track and extended forwardly from the track in substantiallyparallel relationship with the anvil.

2. In combination with a carton stitching machine including a standardprovided with a stitching head and an anvil extending forwardly from thestandard, a track rigidly secured to the standard, a carton end blankholding means comprising a flat relatively rigid ledge adjustablysecured to the track for adjustment from and toward the standard andextended forwardly from the track with the anvil, the ledge on its uppersurface being provided with a resilient carton end blank holding clip.

3. In combination with a carton stitching machine including a standardprovided with a stitching head and an anvil extending forwardly from thestandard, a track rigidly secured to the standard, a carton end blankholding means comprising a fiat relatively rigid ledge adjustablysecured at one end to the track for adjustment from and toward thestandard and extended outwardly from the track in substantially parallelrelationship with the anvil, the ledge at its free end being slantedslightly downwardly and on its upper surface being provided with aresilient carton end blank holding clip, and a shelf for holding a pileof carton body blanks adjustably mounted for vertical adjustment on thestandard.
